Thanks Wolfgang for pointing the direction.

My effort so far gave the following:

%%%%
\setuppapersize[S4][S4]
\setupinteraction[state=start,click=no]

\definefield
    [Choice][radio][ChoiceSetup]
    [yes,no]

\definesymbol [YesS] [Y] %[\ding{52},color=red] %% Not successful in getting the symbols I want to work
\definesymbol [NoS] [\getglyph{Dingbats}{\char10008}] %[\ding{56},color=red]
\definesymbol [BlankS] []

\definesubfield[yes][ChoiceSetup][YesS,BlankS]
\definesubfield[no][ChoiceSetup][NoS,BlankS]

\copyfield [no] [no1]
\copyfield [no] [no2]
\copyfield [no] [no3]
\copyfield [no] [no4]

\setupfield[ChoiceSetup]
    [width=2ex,
     height=2ex,
     frame=on,
     background=screen]

\starttext

\hbox to \hsize
    {\field[no1] A: correct \hfill \field[yes] maybe \hfill \field[no2] incorrect \hfill \field[no3] huh?}

\starttabulate

    \field[no1] $x$ \NC \field[no2] $-x$ \NR %% can't figure out how to delink these radio fields from the above
    \field[no3] $\pm x$ \NC \field[yes] $|x|$ \NR

\stoptabulate

\stoptext
%%%%

My intention for including this is not for someone to help debug this but to show the limit of my coding skills.

I was really hoping for a working example of a multiple choice quiz since ConTeXt was originally designed for educational purpose.

Thanks anyway.

Hi,

I am new to ConTeXt but have been using LaTeX for years. Just before I came across ConTeXt, I ran across Acrotex eDucation Bundle. One of its packages allows us to create multiple choice quizzes which has some self-harming features when done on screen. It also has a paper equivalent.

I am wondering if anyone is willing to share his/her setups for multiple choice, with or without the self-harming feature. I am also wondering if ConTeXt has that self-harming feature too. If it can, I hope too see an example of how it can be done.

Take a look at the widgets manual: http://pragma-ade.nl/show-man-13.htm
